Are those Christmas lights in Ontario? Nope it's a map of corn (red) vs soybean (grn) grown in 2013

Here is the image that Andrew Davidson mentions....much greater detail.

Hello All: The space-based maps shows here are actually highly accurate (corn = 92%; soybean = 88%). The maps are validated using thousands of ground-based observations collected by our field crews. We are pretty confident that our output maps are of high quality.

So why does the first map not look "right"? It is not actually a problem with the data; rather, it is a by-product of the way that the map-making software renders images at such a broad geographic scale. If you were to zoom into the map to see greater detail, you would see highly detailed maps of field patterns (e.g. http://t.co/NJ7t7LnzZb). But, as you zoom out so that the map covers a greater area, our mapping software sub-samples the map for faster display. As a result, the output becomes overly generalized, and some finer-resolution detail is lost.

To illustrate this, compare the amount of red in the map I link to above to the amount of red in the more generalized map at the top of the page. They look very different, even though they are different "views" of the same map! The difference is due to the map generalization described above.

Feedback on these maps from farmers and producer groups are important to us. However, as I note above, a visual assessment based on the large-area map leads to misleading conclusions because of the rendering issue. But, once we have created versions of these maps that allow zooming -- e.g. in google earth format -- such an assessment would certainly be possible.

If you are interested in further evaluating our data, or for any further questions relating to these maps or what we do, feel free to email me (Andrew.Davidson@agr.gc.ca) or follow me on Twitter (@AndrewMDavidson).

The images are interesting but the feedback from farmers is that the first one is not accurate.

It must be picking up forests and hay or something else...seems like too much green.

‘It’s another blow’: Farmers deal with surging fertilizer prices ahead of seeding

Fertilizer is an essential part of Kevin Peters’ farm in southwestern Manitoba. But since Israel and the U.S. attacked Iran, the average price of urea fertilizer, which is widely used around the world, has skyrocketed, surging around 30 per cent over the last week. Peters says the interruption in supply didn’t come as a huge surprise to him. “We deal with geopolitical issues all the time with markets, be it pork, be it grain, and now fertilizer,” he said. “There’s always some disruption seeming to happen somewhere in the world that is changing our daily prices.” Peters says he pre-purchased his fertilizer for this farming season back in the fall but is concerned about prices later this year when he has to buy fertilizer again. “We’ll see what the market looks like in eight months,” he said. Like Peters, Andrew James also pre-bought his fertilizer in the fall for his farm in Anola, Man., and he says he is happy he did. “My fertilizer bill for that (at the time) was around $350,00

From a Piece of Wire to Contaminated Feed: Preventing Foreign Material Hazards in Beef Cattle Operations

Foreign material and toxin consumption by beef cattle can lead to significant health problems, reduced performance and economic losses. Canadian cattle producers take great pride and care in how they manage their farms and ranches, from providing proper nutrition to stewarding their land and ensuring excellent animal care. Yet even with the best intentions, foreign materials and toxins can quietly find their way into feed, water or pastures. Understanding where they come from and how to prevent exposure is a key part of protecting your herd. Foreign materials and toxins often slip in through everyday farm activities such as repairing fences, running equipment, feeding hay or dealing with weather-stressed crops. A small piece of wire, leftover net wrap or contaminated feed source might not seem like much, but if consumed by cattle, it can trigger health issues, lost performance or even death.

Principal field crop areas, 2026

Canadian farmers expect to plant more canola, barley, soybeans and corn for grain in 2026, while they anticipate area seeded to wheat, oats, lentils and dry peas to decrease compared with the previous year. Wheat At the national level, farmers anticipate planting 26.7 million acres of wheat in 2026, down 1.1% from the previous year. If this anticipation is realized, national wheat area would remain well above the five-year average, despite a decrease from 2025, which would likely be attributable to continued strong global demand. Producers expect spring wheat area to edge down 0.1% to 18.8 million acres in 2026. They anticipate durum wheat area to decrease 2.4% to 6.4 million acres, while they expect winter wheat area to fall 6.7% to 1.6 million acres. Farmers in Saskatchewan anticipate planting 13.9 million acres of wheat in 2026, down 1.0% from the previous year. Producers expect spring wheat area to fall 0.6% to 8.7 million acres, while they anticipate durum wheat area to remain
